Then, far away from the rest, on the top right is a car combining high efficiency and insane acceleration. A car that would, if all the founders’ bets paid off, stand on its own: the Tesla Roadster.

So argues the original business plan.

“At one end of the spectrum, the Tesla Roadster has higher efficiency and lower total emissions than the best of the most efficient cars,” the plan reads. “At the other end of the spectrum, the Tesla Roadster accelerates at least as well as the best sports cars, but it’s six times as efficient and produces one tenth of the pollution.”
